Introducing the exceptional TSQ series pneumatic scraping self-cleaning filter from Hebei Slot Filter Technology Co., Ltd. This cutting-edge filter system is equipped with an automated mechanical scraping mechanism that effortlessly removes particles and impurities from the internal surface of the filter element. Experience unparalleled efficiency as it operates continuously online, ensuring your filtration process remains uninterrupted.
Discover the superb TSQ series scraping self-cleaning filter, specifically crafted for handling high viscosity liquids up to an impressive 800,000 mPa.s. This marvel of engineering offers a versatile filtration degree ranging from 25-1500μm, allowing it to swiftly and effectively scrape impurities off the filter element surface. Ideal for applications involving water and a variety of viscous liquids, it excels at maintaining impeccable cleanliness and operational efficiency.
[Filtering Status] As the liquid gracefully enters our state-of-the-art filter, it seamlessly navigates past the innovative scraper, smoothly flowing from the inside to the outside of the cutting-edge filter element. Here, impurities elegantly settle on the inner element surface, ensuring only the purest liquid exits from the outlet. Over time, as impurities accumulate, the pressure drop gradually increases, signaling the filter's exceptional ability to capture and contain contaminants.
[Cleaning Status] In a display of engineering brilliance, the scraper glides downwards, effortlessly guiding impurities to the bottom. As it ascends, remaining impurities are naturally propelled to the top of the filter element, where they are delicately flushed off by the liquid. This elegant choreography repeats as the scraper descends once more, consistently ensuring impurities are effectively removed. Remarkably, this entire cleaning process allows the filter to function continuously online, maintaining optimal performance.
[Purging Status] With several meticulous cleaning cycles completed, impurities gradually accumulate. At this point, it becomes necessary to periodically open the valve, efficiently purging the high impurity concentration waste liquid. Notably, this waste liquid can be recovered if desired, highlighting the filter's sustainable and eco-friendly design.
